SC572: Radiometric Calibration of Remote Sensors
A remote-sensing radiometer looks at a target of interest and generates a numeric output signal, often a digital number, voltage, or current. What does this number mean? Calibration is the process of relating this number to a radiometric quantity such as watts. This course reviews radiometric terminology and concepts and uses them to illustrate methods for calibrating passive and active remote sensors. The approach throughout the course is to express the measurement as a measurement equation with uncertainties that drive the calibration methods and requirements. Examples are shown with ground-based, airborne, and space-based sensor systems. The topics include calibration philosophy, radiometry review, calibration standards and traceability, atmospheric effects, uncertainty analysis, calibration methods for thermal infrared sensors, calibration methods for uv, visible, and near-infrared sensors, field of view and angular response, spectral response, polarization response, and imaging systems calibration.
